Haystack

Find the needle you're looking for.

Search doesn't have to be hard. Haystack lets you write your search
code once and choose the search engine you want it to run on. With a
familiar API that should make any Djangonaut feel right at home and
an architecture that allows you to swap things in and out as you need
to, it's how search ought to be.

Haystack v2.0.0 features a huge number of improvements as well as
some backward-incompatible changes. Some of the highlights are:

Multiple backends (you have a Solr & a Whoosh index, or a master Solr & a slave Solr, etc.)

An Elasticsearch backend

Big query improvements

Geospatial search (Solr & Elasticsearch only)

The addition of Signal Processors for better control

Input types for improved control over queries

Rich Content Extraction in Solr

This update is recommended for most installs. If you're relying on
Xapian, you may want to experiment with it but be warned that it's
development stalled early in the v2.0 effort.

Enjoy!
